IM PROVEM iENT IN GAS-GENERATO RS.

Specification forming part of Letters Patent No. 216,1 [9, dated June 3,1879; application filed March 3, 1879.

To all whom it 'may concern:

Be it known that we, CYPRIEN TEssI DU MoTAY and ERAzM J. JERzMANowsKI,both of the city of New York, N. Y., have invented a new and usefulImprovement in Gas-Grenerators, of 'which the following is a full, true,and exactdescription, reference being had'to the accompanying drawings.

Our invention has relation to the construction of an improvedgas-generator and to superheating contrivances in the walls of the same.

In the arrangement shown, which is the best form known to us, thegenerator is double, having two independent gas-generatin g chambers andsuperheaters arranged in the walls surrounding each of these chambersand in the intervening partition, and the air or steam to be superheatedis first passed through the superheaters in the side and end walls ofthe generating-chambers, and then through the superheaters in thepartition separating the same.

In the operations of gas-making, in which currents of heated steam orair are injected into a generating-chamber, it is of the utmostimportance that the steam or air enter the generating-chambers as hot aspossible; and our contrivance has in view the bringing of said steam orair to the hottest possible condition, and also of enabling a steadyheat to be maintained, notwithstanding the fact that one or the other ofthe generators is out of use; and we have found that asuperheatingchamber containing a considerable quantity of cast-iron isvery effective in producing this result. The cast-iron so contained iuthe superheating-chambers is believed to be benecial from the rapiditywith which it receives and parts with its heat, and also from the factthat hot iron becomes readily oxidized, exerting a considerable effectin purifying the gas, if gas is passed through it, and takes from thegas a certain amount of oxygen, thereby reducing it to carbonio oxide.

In the best arrangement shown a double generator` is made use of, thewalls of each of the generators being illed with superheatingspaces, andthe partition between also containing a superheater and the cast-ironbricks referred to.

` Our invention will be clearly understood from the accompanyingdrawings, in which- Figure 1 represents a vertical longitudinal sectionon the line e z through Fig. 2. Fig. 2 represents a horizontal sectionthrough Fig. 1, taken on the line a: Fig. 3 is a vertical sectionthrough Fig. 1 on the line .y y. Fig. 4 is a'vertical section throughtheline z z.

A represents generally the setting of the two generating-chambers B andC, which may be constructed in any of the well-known forms, and shouldbe provided with conical fire-brick grate-bars G G. One ofthe chambersis shown closed by a sand-seal, the other by a balanced valve, and thissecond chamber C is provided with a fuel-supply tube, for a patent forwhich we have previously applied. Superheatingchambers N are built inthe ends and sides of both generators, andare constructed preferably asshown in Fig. 4, in which arepresents a central partition provided withlongitudinal projections h. Projections 7c are also provided either inau adjoiningpartition similar to a or in the brick-work of theapparatus, alternating with the, projections h, and blocks b areprovided, filling the spaces between the prejections h and the sides andthe projcc- Y tions k and the spaces in the central partition, a.

It will `thus be seen that the air or steam passing through thesechannels is necessarily largely diverted from a straight course, andfollows a zigzag or irregular direction.

The air or steam enters the superheater through pipes K, and passes intothe space L above the superheating -passages This space is continued bythe passages p along the sides of the generator. Having passed downwardthrough the side passages it is ded livered into the channel nthroughthe bottom of the generators, and thence passes into the chamber W atthe bottom of the separatingpartition. This chamber contains asuperheater provided with cast-iron blocks, as pred viously described,and is built up as follows: Transverse brick-work supports c are placedin tiers having their lengths running with the length of the setting.These square supports are placed alternately, as is clearly shown-inyFig. 3. Upon these, and at right anglesito them, are laid a series ofcastiron blocks, g. These are also laid alternately, as is clearly shownin Fig. 1. The brick-Work supports e need not be attached permanently tothe apparatus, but the Whole superstructure may be built up like aseries of alternate bricks, each layer resting on the one below. Thesteam or air passes from thetop oi' this central chainber by pipe P.

Itwill be seen that the gas passing up this superheater necessarilypursues a veryirregu lar course, and is brought in contact with thehighly-heated masses of brick-Work and iron, and passes from the pipe Pin a very hot condition.

lt will also be seen that this superheater Will be heated by either ofthe retorts B or C, but, of course, better when both are in operation.

What We claim as our invention, and desire to secure by Letters Patent,is*

l. A double gas-generator provided with a central dividing partition,and with superheating passages in the end and side Walls of bothsuperheaters, and with a superheating-ehau1-y in the dividingpartition,which superheater is provided with alternate blocks of iire-clay andcast-iron, substantially as described.
